What Is an ETF?
An ETF, or exchange-traded fund, is a fund that trades on an exchange like a stock and can hold many assets inside it.

Key takeaways
An ETF is a basket
One ETF can hold hundreds or thousands of stocks or bonds. Buying one share can give exposure to a broad market, sector, country, or strategy.
Costs matter
Many ETFs charge an ongoing expense ratio. Lower costs do not guarantee better results, but high costs create a hurdle that returns must overcome.
ETFs still have risk
Diversification can reduce company-specific risk, but an ETF can still fall when the market or asset class falls. Match the ETF to the goal and timeline.
Worked example
Reading an ETF quickly
Before buying, check what market it tracks, how much it costs, whether it distributes or accumulates income, and whether currency exposure matters.
Common mistakes
Assuming every ETF is diversified just because it is an ETF.
Ignoring currency, tax, domicile, or distribution details.
Buying a sector ETF when the goal calls for broad market exposure.
